Application filed April. v10,

This invention relates to burners forgas heaters, and it has for its.primary object to provide a novel; and improved gas burner for domesticgas heating stoves of that type in which the gas iszsupplied through aplurality of relatively spaced grids to tubular clay radiants superposedupon the burner.

A further object is to structurally improve the gas burner disclosed inPatent No. 1,486,665, granted March 11, 1924, to Holloway and Kielberg,for insuring a more uniform and even distribution of the gas to thevarious grids.

In describing the invention in detail, reference is herein had to theaccompanying drawings, in which- Figure 1 is a side elevation of theinven-.

tion;

Figure 2 is a vertical longitudinal section of the same; and- Figure 3is an enlarged section on line 33, Fig. 2.

Referring to said drawings, 1 indicates the substantially upright sidewalls, and 2 25, the fiat top of a horizontal burner shell or casingwhich is of approximately U-shape,

inverted. Seamed to the lower edges of said side walls 1 are theopposite edges of a sheet metal member 3 which forms a bottom forsaid-casing, said bottom member being downwardly bowed intosemi-cylindrical form, as shown at 3*, throughout a substantial portion,preferably about two thirds, of its length measured from the inlet endof the casing. The opposite end portion 3 of said bottom member isupwardly-bowed into substantially semi-cylindrical form. Otherwiseexpressed, said bottom member 8 is reversely bowed, or troughed, inopposite end portions thereof.

A semi-cylindrical sheet-metal member 4 complements the portion 3 of thebottom 3 of the casing for forming a tubular passage 5, as in Patent No.1,486,665 hereinbefore ture is conducted for delivery to the overlyingdistributing chamber or manifold 6. Said tubular passage terminates oropens into the manifold chamber at a point more 0 or less closelyadjacent to the inclined de fleeting wall 3 which is formed intermediatereferred to, through which the gaseous mix- 1 92s..

jacent portion of said deflecting wall 3 and which is adapted partially.to divide and spread the infiowing stream of the coin bastible mixture.q I A The tubular passage 5, whereby the mix ture i'shohdu'cted to orpast the midway point in the length of the casing obviously,

restricts or lessens the capacity of the adjacent end portion of thechamber 6, and the provision of the upward or reverse cross sectionalcurvature of the bottom portion 3*, disposing said portion insubstantial alinement with the member 4, is designed correspondingly toreduce the capacity of the opv The admission of the gaseous mixture tothe distribution chamber 6 at a point somewhat past the midlengththereof effects a substantially uniform distribution of said mixture tothe various grids 8 which are mounted in spaced relation in the top 2 ofthe burner casing. One or more suitably located ports 9 may, if need be,be provided in the member 4 for admitting to the inlet end of saidchamber any additional quantity of the mixture required to' more nearlyequalize the supply pressure in said end with that of the opposite end.

What is claimed is+- 1. A burner for radiant gas heaters, comprising asheet metal manifold casing having burner rids mounted in the topthereof, said casing aving depending side walls and a bottom attached tosaid side walls, said bottom having one end portion shaped to form anupwardly facing trough, a semicylindrical member located in complementalrelation to said trough for forming a tubular fuel-conducting passage,the opposite end portion of saidbottom being reversely troughed'topresent interiorlv of said casing a wall substantially corresponding toand alined with said semi-cylindrical member and forming the bottom of amanifold chamber having uniform shape and capacity throughout, the lastmentioned wall being spaced fromthe inner end of the latter to form afuel delivery opening. i p

2. A burner for radiant gas heaters, comprising a manifold casing havinga bottom shaped in opposite end portions thereof to ,form reverselyfacing longitudinal troughs,

and a member located'interiorly of said casing disposed in complementaltube-forming relation to the inwardly facing trough and in substantiallyalined relation to the walls of the outwardly facing trough thereby toform a manifold chamber of uniform shape and capacity throughout itslength, said member terminating at its inner end in spaced relation tothe adjaeentend of the last mentioned trough to form an intermediatefuel delivery opening.

3. A burner for radiant gas heaters, comprising a manifold casing havinga bottom shaped in opposite end portions thereof to form reverselyfacing longitudinalv troughs separated by an inclined wall, a member 10-cated interiorly of said casing complementing the upwardly facing troughfor forming a tubular fuel supply passage, said member being terminatedat its inner end in spaced relation to said inclined wall for forming afuel delivery opening into the manifold chamber, the walls of thedownwardly facing trough and the said member being substantially alinedfor equalizing the capacity of said chamber throughout the length of thelatter, said complementing member having a port therein intermediate itsends.

In testimony whereof, I afiix my signature.
